CHURN-IVIOTOB.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed October 6,1906. Serial No. 337,744.

T0 at w/wm, it may concern.-

' Be it known that I, EMORY W. COLE, a citizen of the United States, residing at Alto, in the county of Cherokee, State of Texas, have invented certain new and useful Improvements in Churn-Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a churn-motor, and particularly to a manu ally-operated driving mechanism.

The invention has for an object to provide an improved construction and arrangement of the dasher-operating means and of the driving connection therefor, whereby the churn may be operated with the minimum expenditure of power and secure the most efiicient results.

Other and further objects and advantages of the invention Will be hereinafter set forth,

and the novel features thereof defined by the appended claims.

in the drawings, Figure 1 is a perspective showing the invention. Fig. 2 is a rear view thereof with the seat removed, and Fig. 3 is a detail perspective of the preferred form of driving-chain.

Like numerals refer to like parts in the several figures of the drawings.

The numeral 1 designates the base, which may be of any desired character and is provided at the front with opposite standards 2, braced in any preferred manner-for instance, at 3 at their bases and provided with the bracing-posts 4, extending from the top thereof to the rear of the base to provide a support for the driving mechanism. Each of the standards is provided with a slot 5, adapted to receive the cross-bar 6, upon which the plunger 7 is pivotally mounted at its upper end 8. The churn, as shown by dotted lines in Fig. 1, is adapted to rest upon an adjustable bottom 9, which may be dis-' posed at any desired elevation by means of the cleats 10, provided on the inner faces of the standards to receive and support the bottom 9.

The plunger is driven from the shaft 11, which is pivotally mounted in the upper portions of the standards 2 and provided at its opposite ends with fly-wheels 12. One of the spokes of each of these wheels is pro- Vided with slot 13, in which the upper end of the pitman 14 is adjustably mounted by means of the clamping-nut 15 thereon. By shifting its point of connection radially to the axis of the wheel the length of stroke of the plunger may be adjusted, and this adjustment may also be varied to a greater extent by shifting the bottom upon which the churn rests to a different elevation.

For the purpose of driving the shaft 11 a sprocket 16 is disposed thereon, over which the chain 17, of any desired character, ex tends to the sprocket 18, which is mounted upon the driving-shaft 19, journaled in the lower portion of the braces 4. When it is desired to drive the churn entirely by foot power, this shaft is provided with the cranks or treadles 20, which are disposed adjacent to the seat 21, mounted upon the base.

Under some conditions it is desirable to drive the churn by hand, and for this purpose the shaft 23 is mounted in the braces 4 and provided with the driving-sprocket 24, in mesh with the chain 17 and having an operating crank or handle 251 If it be desired to assist this motion by the foot, a crank 26 may be formed on the shaft'23 and a pitman extended therefrom to the treadle 28, pivotally mounted at 29 upon the base. When using this latter mechanism, it is frequently desirable to shorten the length of the chain by removing a number of the links thereof and disconnecting them from the sprocket 18 to run only over sprocket 24. This may be done by using any form of detachable link for the chain-for instance, the well-known link shown in detail in Fig. 3, where the reduced portion 30 permits the hook 31 of the adjacent link to be readily disconnected therefrom when the parts are swung in proper position and the chain correspondingly adjusted to the length desired. 1

1n the operation of the invention it will be seen that the means forsupporting the churn and driving the plunger provide for a stroke of any predetermined length and in a perfectly straight line, so as to secure the most eflicient and desirable churning action, which can be adjusted or changed to suit the different conditions of use. The driving mechanism for this plunger provides for a treadle movement by the operator while seated so as to accomplish the churning with the lea st ex penditure of power or energy, while the same may also be accomplished by the hand connection when the conditions of use render that most desirable.

The invention therefore presents a simple, efficient, and economically-constructed device for manually operating a churn and cffects the churning action in the minimum of time with the least expenditure of energy.

Having now described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. In a device of the class described, a base, slotted standards extending upward therefrom, rearwardly-extending inclined braces from the upper portion of said standard, a driving-shaft mounted at the upper end of said standards, a fly-wheel thereon, a crossbar extending through said slots, a pitman connection from said bar to said wheel, a power-shaft mounted in said braces, and a driving connection therefrom to the drivingshaft.

2. In a device of the class described, a base, slotted standards extending upward therefrom, a driving-shaft mounted upon said standards and provided with a iiy-wheel thereon, a cross-bar, a pitman connection from said bar to said wheel, a series of parallel cleats disposed upon the inner face of each of said standards, and a bottom supported by said cleats and adapted to be adjusted at different heights;

3. In a device of the class described, a base, slotted standards extending upward therefrom, driving-shafts mounted at the upper end of said standards and provided with a fly-wheel thereon, a cross-bar extending through said slots, a pitman extending from said bar and adjustably connected to a spoke of said wheel, a series of cleats disposed upon the inner face of said standards, a bottom adjustably supported by said cleats, rearwardly-extending braces from the upper portion of said standards, a driving-sprocket upon the shaft of said fly-wheel, a chain extending over said sprocket, and a powershaft mounted in said braces and provided with a sprocket to drive said chain.

4. In a device of the class described, a base, slotted standards extending upward therefrom, driving-shaft mounted at the upper end of said standards and provided with a fly-wheel thereon, a cross-bar extending through said slots, a pitman extending from said bar and adjustably connected to a spoke of said wheel, a series of cleats disposed upon the inner face of said standards, a bottom adj ustably supported by said cleats, rearwardlyextending braces from the upper portion of said standards, a driving-sprocket upon the shaft of said fly-wheel, a chain extending over said sprocket, a power-shaft mounted in said braces and provided with a sprocket to drive said chain, a treadle connection upon said power-shaft for driving the same, and a seat supported adjacent said treadle.

5. in a device or the class described, a base, slotted standards extending upward therefrom, driving-shaft mounted at the upper end of said standards and provided with a iiy-wheel thereon, a cross-bar extending through said slots, a pitman extending from said bar and adjustably connected to a spoke of Said wheel, a series of cleats disposed upon the inner face of said standards, a bottom adjustably supported by said cleats, rearwardlyextending braces from the upper portion of said standards, a driving-sprocket upon the shaft of said iiy-wheel, a chain extending over said sprocket, a power-shaft mounted in said braces and provided with a sprocket to drive the chain, a treadle connection upon said power-shaft for driving the same, a seat supported adjacent said treadle, a powershaft journaled in said braces above said treadle and provided with a hand-crank and a sprocket carried by the said last-mentioned shaft to engage said chain.
